To all whom it may concern:

Be it known that I, EUGENE SCHNEIDER, a citizen of the French Republic,and a resident of 42 Rue dAnjou, Paris, France, have invented a new anduseful Improved Construction of Bogies, which invention is fully setforth in the following specification.

This invention has for its object to provide an improved construction ofbogie, which is characterized by the feature that its frame is composedof a girder-like structure of reinforced cement which, in addition tothe necessary lodgment for the parts of the socket for the center pinconnecting the bogie to the frame of the vehicle, comprises lodgments orrecesses in which are fixed molded members that form the supports forthe ends of the suspension springs, and that also serve as means of. theattachment for the horn-plates of the pedestal, serving to hold theaxle-box. The said girder-like structure may also have recesses for thelodgment of analogous molded members that serve for the attachment ofthe pivots of the brake block suspension links.

Two constructional forms of the improved bogie are illustrated by way ofexample in the accompanying drawings in which Figures 1 to 4 illustratethe first constructional form.

Fig. l is a Vertical section on the line II of Fig. 2.

Fig. 2 is a half plan of the improved bogie partly in section on theline IIII of Fi 1.

ig. 3 is an end elevation partly in section on the line III--III of Fig.2.

Fig. 1 is a partial cross section on the line IVIV of Fig. 1.

Complementary Figs. 5 and 5 show a vertical longitudinal sectional Viewof a second constructional form of the invention embodying a bogiehaving five wheeled axles, being taken on the line VV in the View shownby the complementary Figs. 6 and 6*. Y

Complementary Figs. 6 and 6 show a plan view of the same, being brokenaway in parts.

The improved bogie which is shown in this first example, with two axles,is characterized by the feature that its frame consists of a girder-likestructure A of rein- Specification of Letters Patent.

forced cement comprising in addition to the necessary lodgment for theparts B and C of its pivot pin socket BCD, also lodgments or recesses ainto which are fixed molded members E that form the supports for theends f of the suspension springs F, and also serve as means ofattachment for the hornplates G of the axle-box pedestal. The connectionbetween the hornplates G and the molded members E may be effected bymeans of ordinary bolts 9.

This improved construction of bogie allows of mounting the reinforcedconcrete frame A very speedily and simply upon the wheeled axles; itbeing sufficient for this purpose to engage the ends f of the springs inthe molded members E and insert the bolts g.

As in the preceding example, the frame of the bogie in the secondconstructional example, embodying five wheeled-axles in the formation,consists of a girder-like structure A of reinforced concrete, comprisinglodgments a for molded members that serve as supports for the ends f ofthe suspension springs F as well as means of attachment for 1thehornplates G of the axle-box pedesta As shown in Fig. 5 one and the samemolded member E may serve as a support for the ends of the suspensionsprings of two adjacent axles.

The girder-like structiu'e A (Figs. 5 and 6) comprises recesses a formolded mem bers E which serve as means of attachment for the pivot pinsh supporting the suspension links H of the brake blocks I.

The brake rigging may of course be of any suitable known type. Flat barsJ hav ing their ends fixed in the cement of the girder-like structure A,may be set in lodgments a to serve as means of attachment for the pivotpins of certain parts of the brake rigging. In the illustrated example,the lever K connected to the rod L for actuating the brake rigging,extends through the lodgments a.

What I claim is 1. In a bogie, a girder-like frame of rein forcedconcrete, and fastening-devices for attaching bogie-accessories seatedin lodgments in the material of said frame.

2. In a bogie, a girder-like frame of rein- Patented Feb. 17, 1920.Application filed March 31, 1919. Serial No. 286,499.
